[HELP] colored text marked by a caption and across multipages
by Wei_Hu＠mtk.com.tw 04 Oct '06

04 Oct '06

Hi all, << 1 >> First, I want to put source codes into my document. I achieve this by using 'verbatim' \starttyping blah blah \stoptyping << 2 >> Then I decide to add colors for these source codes, so I use: \starttyping[option=color,option=commands] blah blah <</color[red]....>> blah blah \stoptyping << 3 >> Finally, I want to refer to this block of source codes in the rest document, so I use: \placefloat[here][listing:sample]{Hello world} \starttyping[option=color,option=commands] blah blah <</color[red]....>> blah blah \stoptyping and refer to it by \in{}[] and \at{}[]. << 1 >> & << 2 >> & << 3 >> work great, however, if the source codes are long enough, and doesn't fit into one page, then the bottom of it will not display. After searching this mailing list, I found some methods: \bTABLE, \starttextbackground ..etc... But none of them can achieve this facility. I can accomplish this facility though LaTeX as described in page 2 ~ page 3 in the attached file. (It uses listings package in LaTeX) All I want is a colored source codes marked by a caption, and I can refe to that source code using \in{}[] or \at{}[] primitives. Are there any ways in ConTeXt can achieve this?

setupformulas: make indentnext=auto the default?
by Sanjoy Mahajan 04 Oct '06

04 Oct '06

The default for setupformulas is indentnext=no, at least from a couple experiments and this line in core-mat.tex (in version 2006.08.08): \c!indentnext=\v!no, What's the view on changing it to indentnext=auto, which seems intuitive at least if one is used to TeX or LaTeX? From the archives, it seems like 'auto' was the default a few years ago, but maybe there was reason to change it to 'no'. -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1.

Hi, I uploaded a beta release. If no further problems with the upgraded figure inclusion and adapted metapost conversion are reported, we will go current (otherwise a changelog will be impossible, even if most changes are not reportable anyway) Hans -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

LilyPond module for LilyPond 2.9.x
by Henning Hraban Ramm 04 Oct '06

04 Oct '06

Yeah, I finally got it working with recent versions of LilyPond! (The most important change was from "linewidth" to "line-width", and I overlooked that far too long...) The module still has lots of issues (e.g. paths for external command like lilypond are hardcoded), but it does what I want it to do. ;-) Could someone please exchange the module in the garden?

Problem with ConTeXt installation
by Jeremy Johnson 02 Oct '06

02 Oct '06

I'm having problems starting ConTeXt with texexec on my Gentoo system. I've installed ConTeXt using the MikTeX Package Manager: "for p in `mpm --list|grep context | tr -s [:space:] | cut -d ' ' -f 4`; do mpm --install=$p; done" followed by a "texhash" and an "updmap" for good measure, and I've upgraded to the latest tetex-3.0_p1-r3 in Gentoo's portage. I've also followed the guide: http://wiki.contextgarden.net/Linux_Installation#Updating_Gentoo_Linux and modified /etc/texmf/fmtutil.d/00fmtutil.cnf by adding a '*' where indicated in the above referenced wiki. followed by texmf-update. BUT: $ texexec --version TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texexec : TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 texutil : TeXUtil 9.0.1 - ConTeXt / PRAGMA ADE 1992-2006 pdfetex: unrecognized option `--alias=context' pdfetex: unrecognized option `--undump=cont-en' kpathsea: Running mktexfmt context.fmt fmtutil: no info for format `context'. tex : unknown context : ver: 2006.07.14 12:08 cont-en : unknown pdfetex: unrecognized option `--alias=context' pdfetex: unrecognized option `--undump=cont-nl' kpathsea: Running mktexfmt context.fmt fmtutil: no info for format `context'. cont-nl : unknown total run time : 5 seconds warning : use 'texmfstart texexec' instead And if I try to process some contex file: $ cat >test.tex <<EOF > \starttext > Hello World > \stopttext > EOF $ texexec test.tex TeXExec 5.4.3 - ConTeXt / PRAGMA ADE 1997-2005 fixing texformat path : .: {!!/home/jeremy/.texmf-config,!!/home/jeremy/.texmf-var,/home/jeremy/texmf,!!/var/lib/texmf,!!/var/lib/texmf,!!/var/lib/texmf,!!/usr/local/share/texmf,!!/usr/share/texmf-site,!!/usr/share/texmf}/web2c/{$engine,} fixing engine variable : pdfetex executable : pdfetex format : cont-en inputfile : test output : standard interface : en current mode : none TeX run : 1 pdfetex: unrecognized option `--alias=context' pdfetex: unrecognized option `--undump=cont-en' This is pdfeTeX, Version 3.141592-1.30.5-2.2 (Web2C 7.5.5) (/usr/local/share/texmf/web2c/natural.tcx) kpathsea: Running mktexfmt context.fmt fmtutil: no info for format `context'.

No! On page 3 there should be a difference between figure 1/2 and figure 2/3, if I understand it right. But there is nothing. page-flt.tex is changed at 2006.09.24 There is also a file core-pos.tex and core-pos.mkii from 2006.09.24 both. > Wolfgang (the younger one?) passports are not allways up-to-date! :-) Wolfgang

## in \def in \sometxt fails with static MP figure
by Sanjoy Mahajan 30 Sep '06

30 Sep '06

Now that \sometxt works with static figures (thanks!), I'm converting from using btex..etex to using \sometxt, to avoid MPenvironments (instead put it in the general .tex environment). But I ran into an error with macro arguments and static figures. Let me know if it's not worth fixing in view of the Mk IV cleanup, and I'll switch to reusable figures (and eventually Linux will support dual core CPUs + suspend to ram, and then I won't notice the processing time much). Here is a small example file: ================= y.tex ======================== \def\2#1#2{\vbox{\halign{##\hfil\cr#1\cr#2\cr}}} \starttext \startstaticMPfigure{fig} label(\sometxt{\2{h}{x}}, origin); \stopstaticMPfigure \usestaticMPfigure[fig] \stoptext ================= y.tex ======================== It produces this texexec.tex (2006.09.28 22:43 beta): ================ texexec.tex ===================== \setupoutput[pdftex] \setupcolors[state=start] \global \loadfontfileoncetrue \starttext \startMPpage beginfig(1); label(\sometxt{\vbox {\halign {##\hfil \cr h\cr x\cr }}}, origin); endfig; \stopMPpage \stoptext ================ texexec.tex ===================== The ## in the expanded argument to \sometxt causes a problem: =================== texexec.log ============== ! Only one # is allowed per tab. l.1 \vbox {\halign {## \hfil \cr h\cr x\cr }} \doTeXtext ... \startcurrentcolor \scantokens {#3} \stopcurrentcolor }\global... \dodofiltersometxt ...er \TeXtext \txtcounter {#1} \expandafter \filtersometx... <argument> ...halign {##\hfil \cr h\cr x\cr }}}, o rigin); endfig; \flushTeXtexts ...llectedmptexts \filtersometxt #1 \sometxt {}\empty \relax \... \writecheckedMPgraphic ...phic \flushTeXtexts {#1} \writeMPgraphic {#1} ... l.9 endfig; \stopMPpage ? =================== texexec.log ============== Alas using \def\2#1#2{\vbox{\halign{#\hfil\cr#1\cr#2\cr}}} leads to a different error (illegal parameter number). But using a reusable graphic works: ==================== yy.tex ===================== \def\2#1#2{\vbox{\halign{##\hfil\cr#1\cr#2\cr}}} \starttext \startreusableMPgraphic{fig} label(\sometxt{\2{h}{x}}, origin); \stopreusableMPgraphic \reuseMPgraphic{fig} \stoptext ==================== yy.tex ===================== -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

btex..etex fails in reusableMPgraphic (2006.09.28 beta)
by Sanjoy Mahajan 30 Sep '06

30 Sep '06

Unless I'm doing something very silly, the following should and I am almost certain did work, but it fails with the 2006.09.28 beta: ================ btex.tex =================== \starttext \startreusableMPgraphic{fig} label(btex in b/e tex etex, origin); \stopreusableMPgraphic outside btex..etex\quad \reuseMPgraphic{fig} \stoptext ============================================ The output says systems : begin file btex-mpgraph-temp at line 42 ! Missing $ inserted. <inserted text> $ <to be read again> _ l.48 _ special_div_ := 10000; ? Here's a snippet from btex-mpgraph-temp.tex: \starttext \startMPXpage " mpgraph:=1; randomseed:=33; _special_div_ := 10000; The underscores in the variable name are upsetting to tex. I haven't tracked down the chain of influence that put them there. Meanwhile the same btex..etex test on a static MP figure works fine: ==================== btex-static.tex ================ \starttext \startstaticMPfigure{fig} label(btex in b/e tex etex, origin); \stopstaticMPfigure outside btex..etex\quad \usestaticMPfigure[fig] \stoptext ==================================================== -Sanjoy `A society of sheep must in time beget a government of wolves.' -- Bertrand de Jouvenal

run a ruby script and use the standard output ???
by Renaud AUBIN 30 Sep '06

30 Sep '06

Hi all, Is it possible to run a ruby script from a context document during its processing (I already know how to do that using \write18 but there is maybe a better way...) then get the output of the script to display or use it into the document. It's a little bit hard to describe so I have a simple example: \starttext \def\vartest{3.124325234543523452435} \write18{ruby ./myscript.rb \vartest XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX} \stoptext with myscript.rb: temp = ARGV[0] puts "\nXXXXXXXXXXXXX " + (Math::sqrt(temp.to_f)).to_s + " XXXXXXXXXXXXX\n" I would store the result of puts into a variable usable within ConTeXt...
